[Freesurfer] Problem with reading GE dicom and reducing the resolution

Hi,

I have received a dataset of high resolution monkey structural scans (0.5 mm * 0.5mm * 0.5mm) collected by GE machines. Now I have two problems that I appreciate if you help me with them, 1- mri_convert can not convert these files to mgh format and I don't now why. Error message says that they are not dicom while even the linux machine detects them as dicom. 2- How can I reduce the resolution to 1mm rather than 0.5 to further use them with freesurfer?

I have attached one of those dicom files to this e-mail. Apparently their name format is also very different from ours.

Best Regards
